Need to send image and text to the server

In my application I need to send image and the note(text of 180) characters to the server.

Now am able to send image and text separately but I need to send together now.

What would be the approach?

Currently am sending image using thread.

// open a URL connection to the Servlet
                FileInputStream fileInputStream = new FileInputStream(
                        sourceFile);
                URL url = new URL(
                        "http://xxx.com/image.php");

                // Open a HTTP connection to the URL
                conn = (HttpURLConnection) url.openConnection();
                conn.setDoInput(true); // Allow Inputs
                conn.setDoOutput(true); // Allow Outputs
                conn.setUseCaches(false); // Don't use a Cached Copy
                conn.setRequestMethod("POST");
                conn.setRequestProperty("Connection", "Keep-Alive");
                conn.setRequestProperty("ENCTYPE", "multipart/form-data");
                conn.setRequestProperty("Content-Type",
                        "multipart/form-data;boundary=" + boundary);
                conn.setRequestProperty("uploaded_file", fileName);
                // conn.setRequestProperty("id", imei);

                dos = new DataOutputStream(conn.getOutputStream());

                dos.writeBytes(twoHyphens + boundary + lineEnd);
                dos.writeBytes("Content-Disposition: form-data; name=uploaded_file; filename="
                        + fileName + imei + lineEnd);


                dos.writeBytes(lineEnd);

                // create a buffer of maximum size
                bytesAvailable = fileInputStream.available();

                bufferSize = Math.min(bytesAvailable, maxBufferSize);
                buffer = new byte[bufferSize];

                // read file and write it into form...
                bytesRead = fileInputStream.read(buffer, 0, bufferSize);

                while (bytesRead > 0) {

                    dos.write(buffer, 0, bufferSize);
                    bytesAvailable = fileInputStream.available();
                    bufferSize = Math.min(bytesAvailable, maxBufferSize);
                    bytesRead = fileInputStream.read(buffer, 0, bufferSize);

                }

                // send multipart form data necesssary after file data...
                dos.writeBytes(lineEnd);
                dos.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd);

                // Responses from the server (code and message)
                serverResponseCode = conn.getResponseCode();
                String serverResponseMessage = conn.getResponseMessage();

                Log.i("uploadFile", "HTTP Response is : "
                        + serverResponseMessage + ": " + serverResponseCode);

                if (serverResponseCode == 200) {

                    runOnUiThread(new Runnable() {
                        public void run() {

                            Toast.makeText(getBaseContext(),
                                    "File Upload Complete.", Toast.LENGTH_SHORT)
                                    .show();
                            File delfile = new File(currentfile);
                            //delfile.delete();
                        }
                    });
                }

                // close the streams //
                fileInputStream.close();
                dos.flush();
                dos.close();

            } catch (MalformedURLException ex) {

                // dialog.dismiss();
                ex.printStackTrace();

                runOnUiThread(new Runnable() {
                    public void run() {
                        // messageText.setText("MalformedURLException Exception : check script url.");
                        Toast.makeText(getBaseContext(),
                                "MalformedURLException", Toast.LENGTH_SHORT)
                                .show();
                    }
                });

                Log.e("Upload file to server", "error: " + ex.getMessage(), ex);
            } catch (Exception e) {

                // dialog.dismiss();
                e.printStackTrace();

                runOnUiThread(new Runnable() {
                    public void run() {
                        // messageText.setText("Got Exception : see logcat ");
                        Toast.makeText(getBaseContext(),
                                "upload failed Please, try after some time ",
                                Toast.LENGTH_SHORT).show();
                    }
                });
                Log.e("Upload file to server Exception",
                        "Exception : " + e.getMessage(), e);
            }
            // dialog.dismiss();
            return serverResponseCode;

        } // End else block

For sending text am using simple http post method.

I need this for my application where we are going to take snapshot and type some thing in edittext box and send.

Try this may helps you

public void WSCall(final String filePath, final String textTosend) {

        try {

            DefaultHttpClient httpclient = new DefaultHttpClient();
            HttpPost httppost = new HttpPost("http://xxx.com/image.php");
            StringBody data = new StringBody(textTosend, Charset.forName(HTTP.UTF_8));
            MultiPartEntity entity = new MultiPartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);
            entity.addPart("uploaded_file", new FileBody(new File(filePath), "image/png"));
            entity.addPart("text", data);
            httppost.setEntity(entity);
            HttpResponse WSresponse = httpclient.execute(httppost);
        } catch (Throwable e) {

        }

    }

First of all, You need this org.apache.httpcomponents.httpclient_4.2.1 jar file and import to your build path.

You can do that in such a way. consider the following

import org.apache.http.NameValuePair;
import org.apache.http.message.BasicNameValuePair;
import org.json.JSONException;
import org.json.JSONObject;

And the declaration :

 private List<NameValuePair> nameValuePairs;

private HttpURLConnection connection = null;
private DataOutputStream outputStream = null;
private String lineEnd = "\r\n";
private String twoHyphens = "--";
private String boundary = "*****";
int bytesRead, bytesAvailable, bufferSize;
byte[] buffer;
int maxBufferSize = 1 * 1024 * 1024;

And the source code is as follows :

try {

            FileInputStream fileInputStream = new FileInputStream(StickerToSend);
            URL url = new URL("Your URL");
            connection = (HttpURLConnection) url.openConnection();

            // Allow Inputs & Outputs
            connection.setDoInput(true);
            connection.setDoOutput(true);
            connection.setUseCaches(false);

            // Enable POST method
            connection.setRequestMethod("POST");

            connection.setRequestProperty("Connection", "Keep-Alive");
            connection.setRequestProperty("Content-Type",
                    "multipart/form-data;boundary=" + boundary);

            outputStream = new DataOutputStream(connection.getOutputStream());

            // ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
                   // Here you can add parameters as follows :

            outputStream.writeBytes(twoHyphens + boundary + lineEnd);

                    // The keyword "type" is the key value and 

            outputStream
                    .writeBytes("Content-Disposition: form-data; name=\"type\""
                            + lineEnd);
            outputStream.writeBytes(lineEnd);

                    // You can assign values as like follows : 

            outputStream.writeBytes("Your value");
            outputStream.writeBytes(lineEnd);
            outputStream.writeBytes(twoHyphens + boundary + lineEnd);

            ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

            outputStream.writeBytes(twoHyphens + boundary + lineEnd);
            outputStream
                    .writeBytes("Content-Disposition: form-data; name=\"sticker\";filename=\""
                            + StickerToSend + "\"" + lineEnd);
            outputStream.writeBytes(lineEnd);

            bytesAvailable = fileInputStream.available();
            bufferSize = Math.min(bytesAvailable, maxBufferSize);
            buffer = new byte[bufferSize];

            // Read file
            bytesRead = fileInputStream.read(buffer, 0, bufferSize);

            while (bytesRead > 0) {
                outputStream.write(buffer, 0, bufferSize);
                bytesAvailable = fileInputStream.available();
                bufferSize = Math.min(bytesAvailable, maxBufferSize);
                bytesRead = fileInputStream.read(buffer, 0, bufferSize);
            }

            outputStream.writeBytes(lineEnd);
            outputStream.writeBytes(twoHyphens + boundary + twoHyphens
                    + lineEnd);

            // int serverResponseCode = connection.getResponseCode();
            String serverResponseMessage = connection.getResponseMessage();

            Log.d("The server response message ", " Server Response"
                    + serverResponseMessage);

            fileInputStream.close();
            outputStream.flush();
            // ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
            InputStream is = connection.getInputStream();
            // retrieve the response from server
            int ch;
            StringBuffer b = new StringBuffer();
            while ((ch = is.read()) != -1) {
                b.append((char) ch);
            }
            String result = b.toString();
            Log.i("Response", result);

            JSONObject jsonobject;
            try {
                jsonobject = new JSONObject(result);
                boolean isPosted = jsonobject.getJSONObject("response")
                        .getString("httpCode").equals("200") ? true : false;

                if (isPosted)
                    mHandler.sendEmptyMessage(POST_SUCCESS);
                else
                    mHandler.sendEmptyMessage(POST_FAILURE);
            } catch (JSONException e) {
                Log.d("the xceptions ",
                        "Xcep in posting status messages are : "
                                + e.getMessage());
            }
            outputStream.close();

        } catch (Exception e) {
            Log.d("Xceptions",
                    "Xceptions are  upload video file  " + e.getMessage());
        }

This piece of code really works very well. I have checked this also. Please feel free if there is any issues.

You can use base64 encoder for encoding image to string (Base 64 encode and decode example code) and make a web service to send this to server. So in that web service you can add multiple inputs
